PIEZA PARA SUJETAR ARMADURAS EN ELEMENTOS DE PIECE TO SUBJECT ARMORS IN ELEMENTS OF
HORMIGÓN ARMADO REINFORCED CONCRETE
DESCRIPCIÓN Pieza para sujetar armaduras en elementos de hormigón armado. DESCRIPTION Part to hold reinforcements in reinforced concrete elements.
CAMPO DE LA INVENCIÓN FIELD OF THE INVENTION
La presente invención se refiere a una pieza que puede ser utilizada en el sector de la construcción, para sujetar armaduras en elementos de hormigón armado. The present invention relates to a piece that can be used in the construction sector, to fasten reinforcements in reinforced concrete elements.
ESTADO DE LA TÉCNICA ANTERIOR STATE OF THE PREVIOUS TECHNIQUE
Como es sabido, durante la ejecución de elementos constructivos de hormigón armado es necesario mantener la correcta posición de las armaduras utilizadas antes y durante el hormigonado, a fin de asegurar un recubrimiento mínimo y una correcta posición de las armaduras que garantice un buen trabajo estructural durante la vida útil del elemento constructivo. Con este objetivo, para la sujeción de armaduras, barras o barras corrugadas en elementos constructivos de hormigón armado, habitualmente se utiliza bien el atado con alambre (de modo manual o con máquina) o bien la soldadura, según se recoge en distintos artículos de la Instrucción de hormigón estructural (EHE-08) (art. 33.2, 69.4 o 69.8) evitando movimientos o desplazamiento indeseados. As is known, during the execution of reinforced concrete construction elements it is necessary to maintain the correct position of the reinforcements used before and during concreting, in order to ensure a minimum coating and a correct position of the reinforcements that guarantees a good structural work during the useful life of the constructive element. For this purpose, for the fastening of reinforcements, bars or corrugated bars in reinforced concrete construction elements, it is usually used either the wire tying (manually or by machine) or welding, as collected in different articles of the Structural concrete instruction (EHE-08) (art. 33.2, 69.4 or 69.8) avoiding unwanted movements or displacement.
La primera solución (el atado con alambre) normalmente se utiliza en la elaboración de ferralla tanto en el taller de ferralla como en obra mientras que, la segunda (la soldadura), se emplea usualmente en los trabajos efectuados en taller. The first solution (wire-bound) is normally used in the fabrication of ferralla in both the ferralla workshop and on site, while the second (welding) is usually used in the work carried out in the workshop.
El atado manual con alambre ha sido siempre utilizado en las armaduras de todos los elementos constructivos de hormigón armado en una obra, y supone un mayor tiempo de ejecución. Posteriormente, la necesidad de una mayor sistematización más allá del atado manual motiva la aparición del atado con máquina (pistola) que normalmente es empleado para elementos superficiales y con gran cantidad de puntos de atado (muros, losas, placas, etc.) debido a su rapidez de ejecución y a su ahorro en mano de obra. Aun así, y aunque la utilización de la pistola para el atado de armaduras supone una mejora respecto al atado manual, ambos sistemas presentan ciertos inconvenientes, a saber: Manual wiring with wire has always been used in the reinforcements of all the reinforced concrete construction elements in a work, and it means a longer execution time. Subsequently, the need for greater systematization beyond manual tying motivates the appearance of machine-bound tying (gun) that is normally used for surface elements and with a large number of tying points (walls, slabs, plates, etc.) due to its speed of execution and its savings in labor. Even so, and although the use of the gun for the tie of armors supposes an improvement with respect to the manual tie, both systems present certain disadvantages, namely:
- Ambos requieren mano de obra para su instalación. o La necesidad de muchos puntos de atado para mantener la correcta posición de las armaduras, supone una gran cantidad de mano de obra. - Both require labor for installation. o The need for many tie-down points to maintain the correct position of the reinforcements implies a large amount of labor.
- Ambos implican la utilización de elementos o sistemas auxiliares adicionales. o Tanto en el atado manual como con máquina es necesaria la utilización de sistemas auxiliares como las tenazas, en el primer caso, o las pistolas de atado, en el segundo, durante el proceso de atado. - Además, las pistolas de rollo de alambre utilizadas habitualmente presentan distintos problemas específicos: o Son herramientas que a menudo se atascan y necesitan un mantenimiento continuo. o Tienen un peso considerable, lo que dificulta el manejo del operario. o Llevan una batería recargable, siendo necesaria la conexión a la red eléctrica para su uso continuado en el tiempo. Además, la batería tiene una duración limitada y debe cambiarse tras determinadas horas de uso. - Both involve the use of additional auxiliary elements or systems. o In both manual and machine tying, it is necessary to use auxiliary systems such as pliers, in the first case, or tying guns, in the second, during the tying process. - In addition, wire roll guns commonly used have different specific problems: o They are tools that often get stuck and need continuous maintenance. o They have a considerable weight, which makes the operator's handling difficult. o They carry a rechargeable battery, the connection to the mains being necessary for its continued use over time. In addition, the battery has a limited duration and must be changed after certain hours of use.
Por otro lado, entre los inconvenientes derivados del atado con soldadura cabe destacar los siguientes: o El atado con soldadura habitualmente se realiza en el taller de ferralla y no en la propia obra. Esto es debido a que la maquinaria empleada es de difícil transporte y es necesario su manejo por un operario cualificado. o Una vez soldadas las armaduras, la posición final del elemento es invariable, y no se puede realizar ningún tipo de modificación puntual o de ajuste a las condiciones finales de obra. EXPLICACIÓN DE LA INVENCIÓN On the other hand, among the disadvantages derived from the tied with welding it is possible to emphasize the following: o The tied with welding is usually carried out in the ferralla workshop and not in the work itself. This is due to the fact that the machinery used is difficult to transport and its handling is necessary by a qualified operator. o Once the reinforcements are welded, the final position of the element is invariable, and no type of punctual modification or adjustment to the final work conditions can be made. EXPLANATION OF THE INVENTION
A la luz de lo anterior, la invención propuesta es una buena solución para sujetar armaduras en elementos de hormigón armado ya que resuelve los problemas de los sistemas tradicionales de atado con alambre y soldadura anteriormente expuestos. Cuando hablamos de armaduras, entendemos también que puede aplicarse indistintamente a armaduras, barras o barras corrugadas, haciendo referencia al mismo término. In the light of the foregoing, the proposed invention is a good solution for fastening reinforcements in reinforced concrete elements since it solves the problems of the traditional wire-tying and welding systems discussed above. When we talk about armor, we also understand that it can be applied interchangeably to armor, bars or corrugated bars, referring to the same term.

EXPOSICIÓN DETALLADA DE MODOS DE REALIZACIÓN DETAILED EXHIBITION OF REALIZATION MODES
En la figura 1 se ilustra la pieza de la invención donde puede apreciarse que el hueco interior (1) puede tener una forma curva. En la figura 2 se ilustra la colocación de la pieza en las armaduras. En las figuras 1 y 2 puede verse que la abertura (2) de entrada al hueco interior (1) es biselada. Para demostrar que la pieza para sujetar armaduras cumple con los requerimientos de obra, se ha realizado un ensayo de aplicación práctica para la sujeción de armaduras en una parrilla en posición vertical (retícula de armaduras que se cruzan formando un plano vertical, similar al armado requerido en un muro de hormigón armado). Los elementos utilizados en el citado ensayo han sido los siguientes: - Armaduras verticales de 10 mm diámetro, con una longitud de 300 cm y separadas cada 20 cm. Figure 1 illustrates the part of the invention where it can be seen that the inner hollow (1) can have a curved shape. Figure 2 illustrates the placement of the piece in the reinforcements. In Figures 1 and 2 it can be seen that the opening (2) for entering the inner recess (1) is beveled. In order to demonstrate that the piece to hold reinforcements meets the requirements of the work, a practical application test has been carried out to hold reinforcements in an upright grid (reinforcement grid that intersects forming a vertical plane, similar to the required assembly in a reinforced concrete wall). The elements used in the aforementioned test were the following: - Vertical reinforcements of 10 mm diameter, with a length of 300 cm and separated every 20 cm.
- Armaduras horizontales de 10 mm diámetro, con una longitud de 200 cm y separadas cada 20 cm. - Pieza para sujetar armaduras formada por chapa metálica rectangular de dimensiones 30 x 40 x 0,5 mm (ancho x alto x espesor), con dos huecos (1) en su interior con forma elíptica de 1 1 mm de altura por 15 mm de anchura cada uno de ellos, quedando abierta en uno de sus extremos mediante una abertura (2) de 8 mm de ancho, biselada para facilitar encajar la pieza en el elemento a sujetar. - Horizontal reinforcements of 10 mm diameter, with a length of 200 cm and separated every 20 cm. - Piece to hold reinforcements formed by rectangular sheet metal of dimensions 30 x 40 x 0.5 mm (width x height x thickness), with two holes (1) inside with an elliptical shape of 1 1 mm high by 15 mm width each of them, being open at one of its ends through an opening (2) 8 mm wide, bevelled to facilitate fitting the piece into the element to be fastened.
Los pasos que se han seguido para el procedimiento de ensayo para sujeción de armaduras en posición vertical son los siguientes: The steps that have been followed for the test procedure for securing reinforcements in an upright position are the following:
1. En primer lugar, y a partir de las esperas dejadas en la cimentación, se colocan las armaduras verticales, marcando con tiza sobre ellas la separación de las armaduras horizontales. 1. In the first place, and from the waits left in the foundation, the vertical reinforcements are placed, marking with chalk the separation of the horizontal reinforcement.
2. A continuación, se colocan las armaduras horizontales en su posición y se sujetan mediante la pieza propuesta. Para ello, se sitúa la armadura en la posición horizontal a la altura deseada, colocando la pieza propuesta formando 45° con las armaduras; presionando con la mano, se encaja la pieza propuesta, quedando ambas armaduras perfectamente fijadas. Es conveniente que las piezas para sujetar se coloquen alternando el ángulo que forman con la horizontal entre 45° y 135° en las distintas direcciones espaciales, para así asegurar la estabilidad de las armaduras frente al movimiento horizontal. 2. Next, the horizontal reinforcements are placed in position and held by the proposed piece. For this, the reinforcement is placed in the horizontal position at the desired height, placing the proposed piece forming 45 ° with the reinforcements; pressing with the hand, the proposed piece is fitted, with both armors perfectly fixed. It is convenient that the pieces to hold are placed alternating the angle they form with the horizontal between 45 ° and 135 ° in the different spatial directions, in order to ensure the stability of the reinforcements against horizontal movement.
Cabe destacar que no es necesario sujetar todas las intersecciones de armaduras verticales y horizontales con la pieza propuesta, ya que es posible establecer una alternancia sujetando una de cada dos o más intersecciones, siendo conveniente que los atados o sujeciones queden alineados en las dos diagonales con respecto a la cuadrícula que forma la armadura del muro. It should be noted that it is not necessary to fasten all the intersections of vertical and horizontal reinforcements with the proposed piece, since it is possible to establish an alternation by holding one of every two or more intersections, it being convenient that the ties or fasteners are aligned in the two diagonals with with respect to the grid that forms the armor of the wall.
